WITHOUT knowing, Ian McDonald was ingesting 250 teaspoons of sugar each week.
Hidden in processed foods and beneath labels that claim it's 'lite', Mr
McDonald's high sugar, high carbohydrate diet had him headed down the path to an early grave.
But four months ago, something clicked.
"I was 136kg - the heaviest I have ever been," he said.
"I thought, bugger this, I need to do something about it.
"I heard Matty from The Gym Yamba was looking for someone to 'change a local life' and so I sent him an email and started training with him in April."
Mr McDonald has since cut out all processed foods, refined sugar and altered his diet to suit his goals.
He has three personal training sessions a week with Matt Carlin from The Gym and in his own words, is "a changed man".
"I'm sleeping better, I have more energy, I feel great and I have lost 25kg," Mr McDonald said.
While it has been no easy battle, and he is only half way towards his goal of 90kg, Mr McDonald said he is never going back to what he was.
"I've gone from 6XL to 3XL and in some clothes even a 2XL," he said.
"I have chucked out all my fat clothes except one which is for show and tell."
Mr McDonald's aim is to be down to 100kg by December, and then 90kg in the first few months of next year.
"I'm not planning on dropping kilos in a short period, this is a lifestyle change," he said.
"I realise now I am going to have to exercise for the rest of my life to keep it off, but I love it."
With his family residing in Sydney, Mr McDonald has purposely not shared photos of his transformation on Facebook and plans to surprise them when he hits his goal.
"I may not be Yamba's biggest loser, but I am Yamba's biggest winner."
